Software that
solves
real business problems.
Senior React.js / .NET fullstack engineer with 12 years building platforms in fintech, energy, pharma, logistics, and manufacturing. Backend deep, fullstack fluent, and obsessed with systems that scale, stay compliant, and hold under load.
<fullstack/>
A backend-focused craftsman who designs code that solves the business problem, then optimizes it to the very last bit.
Backend-deep, fullstack-fluent
C# / .NET Core expert who moves natively across React, Next.js, Angular, and Vue, plus the data, cloud, and infra around them.
Full ownership
From architecture to deployment and performance. On critical platforms, the primary point of contact for the issues nobody else can crack.
Built for cross-functional teams
Solid technical leadership and the kind of proactivity and reliability that teammates name first in a recommendation.
Engineering that
moves the numbers.
Big-data analysis engine
Multi-threaded Monte Carlo engine for catastrophic-event probability over a million data points, on Azure Functions and Apache Parquet.
Faster data processing
Orchestrated parallel workflows with timers and Azure Durable Functions to lift large-scale processing throughput by over 30%.
Faster data access
Cut data access time by more than 3x using the flat columnar storage format of Apache Parquet at scale.
Fraud-detection core
Built core payment processing and validation across 10 interconnected REST services on a national UK payments platform.
Across the full stack,
cloud to component.

0612 years, one standard.
- Architected a change-detection system across 6 interconnected configuration types with selective propagation that preserves user customizations from global standards down to site-specific config.
- Built a regulatory traceability export module and a Git-like version comparison system with multi-level change classification for audit readiness.
- Shipped an approval workflow engine with auto-approve, reviewer assignment, state-machine transitions, and full audit trails.
- Designed an event-driven decision and transaction-state engine on Azure Event Grid, with failed transactions retriggered for reprocessing via Durable Functions.
- Raised large-data processing speed by 30%+ with parallel workflows, timers, and Service Bus CRON batching; owned all performance issues.
- Built core payment validation across interconnected REST and SOAP services and a deployment dependency-graph visual tool with Digraph.
- Sped up processing of 1M+ historical consumption records by sanitizing, grouping, and integrating Azure Databricks.
- Built a graph-based energy-balancing module across 50 interconnected UK suppliers in C# / .NET Core.
- Hardened gRPC, HTTP, Cosmos DB, Redis, and Databricks calls with circuit breakers, rate limiting, retries, hedging, and fallbacks.
- Built a customizable 3D visualization tool with 30 drag-and-drop options for real-time rotation, recomposition, and resizing in React.js and Three.js.
- Implemented material-specific manufacturing workflows for F1 steel components with .NET Core and computational geometry.
- Kept Cosmos DB migrations backward-compatible across production releases.
- Built a multi-threaded Monte Carlo engine for catastrophic-event probability over 1M+ data points with Durable Functions and Apache Parquet.
- Cut data access time by 3x+ via Parquet columnar storage and migrated the platform from on-prem to Azure.
- Cut HTA submission time to minutes with a multi-threaded processor generating 800-page documents via Open XML SDK.
- Made storage uploads 8x faster and reduced processing by up to 75% through dotMemory and dotTrace tuning.
- Cut human labor cost by 50% with a custom content-suggestion system.
- Led a greenfield platform end-to-end and built a payment and credit system on Stripe with Nuxt.js, C#, and .NET Core.
- Scaled to 18,000 parallel users per month and reached 1,800 active users in three months.
- Grew company turnover by ~8% per year via automated marketing modules.
- Fullstack delivery on an inventory management suite, the foundation for a decade of senior .NET work.
BSc in Computer Science
What teams say
after working with me.
A master of development. One of the best .NET developers, but the truth is the technology doesn't matter. He understands any language or stack and optimizes solutions to the very last bit. I recommend George for any project, no matter the difficulty.
We worked together on a large cloud migration for the UK's largest cheque processor. His debugging is exceptional. He finds the root cause others miss and devises effective solutions to complex requirements. A dedicated craftsman who always strives for excellence.
George is to programming what Gaudí was to architecture: a complex, advanced mind that transports your project far into the future. Working with him helped us double our product features with direct impact on revenue. If you can afford him, George is the talent you don't want to miss.
A key player in our Azure and .NET projects. His grasp of cloud technology and .NET is impressive. He tackles complex issues and delivers practical solutions that drive the project forward, and he's always ready to help and share insights.
On a greenfield project for Microsoft MBG Group, George was hands down one of the strongest pillars of the team. Best in class on proactivity and reliability. I strongly believe he can be an invaluable asset on any team, as a developer or a technical lead.
George did an exceptional job on the large-scale programme at Cognizant Microsoft Business Group. Proactive, multi-skilled, and self-motivated, with vast knowledge. A valued member and a true asset to any team. I hope to work with George again.
Have a system worth building right?
Open to senior contract and full-time fullstack roles across the EU and remote. Tell me about the platform, the constraints, and the deadline.
